I fail to see why it would be complicated at all. The 7.5 update was minimal.

https://github.com/macports/macports-ports/commit/dd197967ac1c9fb9b489ee4e347a2f5a859f9839#diff-a55581cf79dd67b30d377c9affc5fce6

Reverting back to 7.4 only for old OSes would be trivial to do. In fact, it would make things easier for you, as then you would not have to reinstate the patch removed in.

As you would still use 7.5 on the platforms needing that patch.

7.5 is the legacy 7.x release. Regardless of whether or not users should be using a newer major version, we should not force users back to 7.4 on the majority of systems that can perfectly happily use 7.5
